MOVABLE ADVERTISING DEVICE FOR AEBOPLANES, &0.

Application filed November 11, 1919. Serial No. 337,328.

To all whom z'tmay concern:

Be it known that I, R-A-YMoNo K. B VIER,

' a citizen of the United States, residing at Spokane, in the county ofSpokane and State of lVashington, have invented new and usefulImprovements in Movable Advertising Devices for Aeroplan'es, &c., ofwhich the fpllowing is a specification.

This'in'vention relates to advertising devices and particularly toaerial advertising apparatus, and has for its object to provide thecombination-with an airplane, of an advertising device that is renderedvisible by the operation of an airplane, and-furthermore which providesfor a change of the advertised subject matter while the airplane is inflight; and the invention'consists of the construction, combination anddetails as illustrated in the accompanying drawings and described andclaimed hereinafter.

Figure 1 is a perspective of an airplane disclosing the advertisingfeatures.

Fig. 2 is a perspective of theairplane in an inverted'position.

Fig. 3 is a top plan View of an airplane showing in detail parts of theadvertising mechanism partly broken away.

Fig. 4 is an elevation of the operating mechanism for changing theposition of the advertising sheets.

Fig. 5 is a transverse section on line 5-4;

' of Fig. 3.

Fig. 6 is a transverse section on line 6-6 of Fig. 4.

My present invention broadly contemplates the combination with an aerialvehicle, such for instance as an airplane 2,

means for effectively displaying insignia and particularly fordisplaying advertising'mab ter, and incorporates means for securing a Ichange of the display at will as either while the vehicle may be at restor in flight and also to secure the display of theadvertlslng mediawhile the airplane is flying normally or inverted. i

To that end the invention includes strips or sheets of suitable materialindicated at S finished or so inade as to embody and dlsclose anyadvertising subject matter that may be desired. Preferably, a sheet ofthe advertising media; is exten ed along a surface of the plane asbetween lateral guides 3-3 secured upon and extending along-thelongitudinal edges-v'of the plane and also, if desired, the advertisingsheet or strip S can be protected by a cover or casing portion 4 thatmay be of translucent, or trans parent, or partly transparent materialthat will form a housing over the exposed surface of the advertisingsheet so as to reduce the friction ofthe wind'o'r air upon theSpecifieation of Letters Patent.

surface of the strip, and therefore permit i it to be readily shifted asis desirable to expose difi'erent areas or parts of its length bearing,for instance, different advertising matter. The guide side strips andthe covering sheet 4 may be suitably. secured in place as bylongitudinal cleats -6 riveted or otherwise secured to the edges of thecovering 4 and resting upon the top ofthe marginal strips 3; the rivets7being shown, in the present case, to secure the parts in position.

In the present case I have shown the upper surface of the upper plane Pof the airplane and the lower plane P as provided with these shiftablestrips or advertising sheets S, and the ends of the strips on each planeare respectively attached to winding drums 10 mounted upon suitableshafts 11 that are appropriately j ournaled in bearings at the cornersof the plane, each of the shafts being provided at one, or the other, orboth the rotation of the shaft through power derived from any suitablesource.

ends, if desired, with a means providing for i In this case, an end ofeach of the drum 1 shafts 11 is provided with a bevel gear 12 designedto mesh with a complementary driving gear 13 which is fast on the outerend of a driving rod or shaft 14 appropriately mounted in bearingsdisposed along the edge of the lane as P, and the inner end of this sha14 is provided with a gear 15.

As shown in Fig. 2, the adjacent gears 15 on the ends of co-axial shafts14 are designed to be alternately engaged with a gear 16 on the upperend of a shaft 17 which, in the present case, is mounted in journals 18,Fig. 6, that are formed on or attached to an oscillating carrier orbasemember 19 whichis mounted on the adjacent end of a shaft 20 whichmay be driven by power derived from any suitable source and not hereshown.

On the lower end of the shaft 17 there is secured a gear 17' and this isadapted to engage a master bevel gear 21 on the adjacent end of thedriving shaft 20 so that the shaft 17 may be driven in the desired direction.

Diametrically opposite to the shaft 17 there is another gear shaft 22having a pinion 21 at one end engaging the gear 21 andat its outer end agear 23 adapted to be alternately meshed with either of the gears 15disposed adjacent to the gear 23 and which are fixed on the contiguousends of the shafts 14 mounted on the lower plane P; The shafts 14 on thelower plane are provided with driving gears 13 to engage withcomplementary pinions 12 on the respective shafts of the winding drumsto wind the movable advertising strip 20 on the lower plane.

Preferably, the winding drums at-the ends of the planes are housed as byrespective casings 26 which may be tapered at the front ends 27 toreduce air resistance if desired.

Any suitable means may be utilized to selectively couple the mechanismof one of the strips to be shifted to the actuating means and, in thiscase, the bearing frame 19 may have attached to it the ends of a cable28 lead in opposite directions over guide pulleys 29 and thence to aconvenient position to enable the operator to draw on the chain or cableto draw, through it the carrying frame 19 from one position to another.In this case the cable 28 is lead from the pulleys 29 around to a centerpul-- selecting device.

Ubviously theseveral advertising sheets or strips S may be provided withany desired advertising media as pictures, or signs, or may beadvertisedby the display of the name of the goods or trade-marks.

' By providing a strip to be exposed along the top surface of the topplane and also another strip to be exposed-along the bottom surface ofthe bottom plane it will be seen that these strips will be exposedwhenever ,the airplane is flying in a normal or in a reversed position.

Various changes may be made without departing from the spirit of myinvention as claimed.

I claim:

1. In an advertising device for airplanes, the combination of displaystrips on its upper and lower wings, opposed drums at the ends of saidwings for reversely winding said strips, several actuating shaftsoperatively connected to one end of said drums, means for reversiblyoperating said drums through the medium of said several shafts,

said means comprising a drive shaft and master gear mounted thereon, anoscillating frame pivotally mounted on said drive shaft, diametricallyopposed shafts journaled on said oscillating frame and operativelyconnected at their inner ends to said master gear, and gears on theouter ends of said shaft adapted to engage similar gears on thediagonally opposed ends of said drum actuating shafts, and manuallyoperable means for causing selective engagement of said last mentionedgears.

2. In combination with an airplane a drum at each end of the lower wingand the upper wing of the airplane, a strip secured at its ends to thedrums at the ends of the lower wing, a strip secured at its ends to thedrums at the ends of the upper wing, a bevel gear on the end of eachdrum shaft,

two lower shafts, bevel gears on one end of said lower shafts meshingwith the bevel gears on drum shafts of the drums at the ends of thelower wing, two upper shafts, bevel gears on one end of said upper shaftmeshing with the bevel gears on the drum shafts of the drums at the endsof the upper wing, a bevel gear on the other end of each of said shafts,an operating shaft, a frame fulcrumed on said operating shaft, twoshafts journaled on said frame, a bevel gear on said operating shaft,bevel gears on the inner end of said frame shafts meshing with the bevelgear on said operating shaft, and a bevel gear on the outer end of eachframe shaft adapted alternately to meshwith the gears respectively onthe other end of said upper and lower shafts, when said frame is swungon its fulcrum, and means within reach of the aviator for swinging saidframe.

3. In combination with an airplane a drummountedat each end of a wing ofsaid airplane, a. strip extending over said wing and secured at its endsto said drums respectively, a bevel gear on each drum shaft, two wingshafts journaled on said wing, a bevel gear on one end of said wingshafts meshing with the bevel gears respectively on said drum shaft, abevel gear on the'other end of each wing shaft, an operating shaft, aswinging frame fulcrumed on said operating shaft, a frame shaftjournaled on said frame, a bevel gear on one end of said frame shaftmeshing with a bevel gear on said operating shaft, a bevel gear on theother end of i said frame shaft for alternately meshing with the bevelgears on the other end of said wing shafts when said frame is swung on.its fulcrum, and means within reach of the aviator for swinging saidframe on its fulcrum.

In testimony whereof I have signedimyl name to this specification. v
